cannot install wireless Lexmark X9575 printer after new router

Had two Win 7 Ultimate 64 bit computers with wireless connection (Linksys router) to a Lexmark X9575 printer with no problems. Moved, got Verizon FIOS with a Ultraline 9100EM router. Was able to get (with a lot of hassle) computer 1 to wireless print. (Can't say at this point exactly what I did but the problem was with jobs being stuck in the printer queue. Had to restart the spooler several time and has worked since.) Wireless indicator on printer is full green. I cannot get computer 2 to install a wireless (or even a USB) printer. I have tried everything I know to get it to work, Uninstalled with Yourununstaller - Super mode, (many times) downloaded new 64 bit driver, gone thru install process (many times) Goes to end of install process, says printer is ready for use, but does not work. Tried "Wireless Configurator" also, no go. Control panel - Devices & Printers shows icon with yellow triangle & !. (Says "Series 9500") Properties show "Manufacturer" and "Model" as "Unknown". Seems that there is no driver for this printer. Windows update has no driver for this printer. Other info: When doing the wireless install it says the computer (2) is being used by another computer. I had to type in a bogus name to get past that point. Can't seem to get any help online, forums, Lexmark, etc. Any ideas? Thanks.

FIXED! I went to control panel - administrative tools - print management and deleted the drivers for the X9575. Did another super uninstall and reinstalled with the CD that came with the printer. Problem solved.
